Hm, all dungeon levels are generated in a random way, but they have ONE thing in common => 3 levels and your boss monster/quest item is in the last one. You can only access BF dungeon entry 1 at the moment, because you only have BF key lvl 1.
On the first island you have skeletons, lvl 2
2nd island => mage skellies, spiders, level 4
3rd island => ghosts, Evil Flying eyes, Earth Elementals, all lvl 7.
And I think! All boss monsters are lvl 12.
